In a chowk traffic signals blinks together, but one of them blinks after 8 seconds and the other one blinks after 12 seconds: after how many seconds will both blink together again?
- 48 sec
- 18 sec
- 24 sec
- None of these
Explanation
To find when both traffic signals will blink together again, we need to find the Least Common Multiple (LCM) of 8 and 12.
LCM of 8 and 12:
Prime factors of 8 = 2 × 2 × 2
Prime factors of 12 = 2 × 2 × 3
LCM = 2 × 2 × 2 × 3 = 24
